Douglas Fir
Pseudotsuga menziesii • Softwood
Grain Pattern
Strong straight grain with prominent latewood; shows cathedral patterns around knots and flat-sawn face; medium to coarse texture.
Color Description
Heartwood is reddish-brown to orange-yellow. Sapwood is yellowish-white. This sample shows significant oxidation and darkening to a warm orange-brown patina due to age and light exposure.
Hardness Rating
710 lbf (Soft)
Durability Rating
Moderately Durable; good resistance to decay and rot, though susceptible to insect attack without treatment.
Common Uses
Heavy construction, flooring, cabinetry, trim, boat building, and plywood manufacturing.
Geographic Origin
Western North America (Pacific Northwest, Rocky Mountains).
Market Value & Sustainability
Estimated Market Value
$4.00 - $8.00 per board foot depending on grade and reclamation status.
Wood Age Estimate
30-50 years; the deep orange-brown oxidation and the presence of rough-sawn circular saw marks suggest vintage reclaim material rather than modern lumber.
Sustainability Status
Not CITES listed; IUCN Least Concern; widely available as FSC certified and from managed plantations.
Workability
Generally easy to work with hand and machine tools. Sharp edges are required to prevent tearing of the soft earlywood between harder latewood rings. Glues and finishes well.
Notable Features
Distinctive resinous scent when cut; highest strength-to-weight ratio of all North American softwoods; prominent contrast between earlywood and latewood rings.
Finish Recommendations
Oil-based polyurethane or penetrating oils to highlight the warm color; sanding sealer is recommended to prevent uneven absorption (blotching).
Identification Confidence
High; the distinct 'cathedral' grain, warm orange-red hue, and the specific appearance of the tight knots are classic indicators of Douglas Fir.
